Don't panic! I just dyed two little curls at the back =] just because A) I want to monitor hair growth and a demarcation line makes it easier and B) I am not prepared to damage my hair or deal with the upkeep of a whole head dye, and I don't really like highlights soo... two little curls it was!

I used this pre-lightener, which I got free off Freecycle (thanks to the lovely lady who offered it!)
